Answer:
A. V(x)= (50-2x) ( 35-2x)x
Step-by-step explanation:
The price after tax is £253.87 so to find the original price you have to deduct 6% but first you need to find 6%.
Easiest way to find 6% is by finding 10% or 2% or 1% / whatever you find easiest. For me it would be 1%
If you find 1 % you would then multiple it by 6 to give you 6%
10% is £25.38 (move the decimals 1 unit)
1% is £2.54 (move decimals 2 units)
Always round up
£2.54 X 6 = £15.24
£253.87 - £15.24 = £238.63
Answer:
(3) (1+1)/6
basically you just input the given numbers in x and y
Step-by-step explanation:
X= -11 and x=17 are the answers
Answer:
Radius AC=12
Step-by-step explanation:
AB is a tangent to circle c so the tangent AB is perpendicular to the radius at A.
Then triangle ABC is right triangle at A.
So by Pythagoras theorem,
CB^2=AB^2 + AC^2
37^2= 35^2 + AC ^2
1369=1225 + AC^2
AC^2= 1369-1225= 144
AC=radical AC^2 =radical 144=12
Hope this helps...
(Note: ^ means power)
